Thread: Dynoed My Car Today!

thats a good idea. and deff dont run those temps on a hot day. thats would be asking for it.

usually i see sr20 motors making more tq then hp once the turbo goes past its effiency.

i did 285whp 262wtq @ 16psi on a gtir t28 with s4's. this was done on a jwt ecu that was super rich. my a/f was 10:1 to about 4 grand or so then dropped completely off the charts (the sniffer would read that low so it was super rich).

get your fuel straightened out and some s4's and you should make some very solid SAFE numbers.

stratton.

I know I'm late to this party, but I have to chip in that on my GTi-R T28 and 370's at 4bar, I was rockin 287whp at 20psi (just for the dyno, not everyday) but the duty cycle on my injectors was right at 100%. I was getting dangerously high EGT's, but never detonated. I would definitely second or third that motion to get a good wideband, and I'd upgrade those injectors. The silvias or STi's aren't bad options.

Found some STI's and I got my AEM wideband on yesterday. And I believe robchaos is hooking me up with a new wastegate So should be long for some new numbers, which will most likely be lower because I will run probabaly 16ish lbs.

Good luck man. You will have a lot of fun with that thing. I would get it wherever your injector duty isn't over 80% for daily driving. If you really want a sick powerband you can get an APEXi AVCR and boost by RPM. That way you can come close to maxxing the injectors with a huge midrange, and taper boost to redline to keep things safe.

I did this on my old car. It felt incredible. Would prolly keep up with the VET in lower gears, and was deceivingly fast. Nothing like a big fat powerband in a 4 banger.

Just ordered a new wastegate and sti injectors hopefully next weekend all will be well

Still need a chip though, waiting for erikk to respond back to me.

Dyno sheet is up on the first page!

lol. did you read miko's post exactly what you need.

I have a Calum R/T Ecu and the bin is for s15 inj @ 4bar w/z32 MAF. The car runs beautifully and I haven't messed with the basic tune at all. I am pulling around 18in vacuum @ idle and a/f are stoich (14.7) when cruising around town and under WOT no matter what boost level, I see 11.8-12.1 a/f ratios. The disco has seen 20psi on a cold night and a/f was perfect. Now you can't ask for more than that with an ecu that is plug and play.

I got some STI injectors, just need a chip now :/

That information was for future reference in case someone wondered if there was a bin for the s15 injector setup
